If you've always dreamed of controlling everything in your household from your iPad, you're in luck--you can use a universal remote control app such as iRule to control just about anything in your house that can be controlled. iRule, which starts at $50, lets you control everything from your home entertainment system to your lights, shades, and garage door, using an iPad, a Wi-Fi network, and some specially designed hardware that converts Wi-Fi signals into various types of control (such as infrared, which controls your home entertainment system).
Of course, iRule isn't the only universal control system out there. You'll also find MobiLinc HD, which lets you control devices such as your thermostat, lights, and keypads remotely.
You may have also heard about the fancy new Nest Learning Thermostat; this energy-saving thermostat gives you control via your iPhone, iPad, or Mac.
7. Turn Your iPad Into a Kitchen Tablet
Tablets are great in the kitchen: They're like high-tech recipe books with built-in timers, easy-to-check conversion charts, and the power of the Internet. You can turn your old iPad into a dedicated kitchen tablet by slipping it into a protective cover, or mounting it on a wall or a cabinet, and downloading all your favorite cooking apps. An old iPad is especially great as a dedicated kitchen computer because you can easily swipe through information without having to fumble with cookbooks or scraps of paper--just be sure to invest in a good screen protector, or else you'll end up smearing your screen with flour and butter.
